The stainless steel magnetic drive pump is a positive displacement pump for vacuum suction and squeeze discharge, with some unique properties. Since its invention more than 60 years ago, it has been widely used in various industrial and mining occasions.

The working principle of stainless steel magnetic drive pump

① There is an eccentric bump in the pump cavity. When the flexible blades leave the eccentric block, the volume between the blades increases continuously, creating a vacuum, which makes the liquid continuously sucked into the inlet of the pump cavity.

② When the flexible vane rotates, the liquid is brought into the discharge part by the suction part of the pump chamber.

③ When the flexible blade touches the eccentric bump again, it will bend and be accompanied by a squeezing action, so that the liquid will be discharged from the pump cavity uninterruptedly and without pulsation, thus completing the whole process of suction and discharge.

Flexible Elastomer Technology for Impellers

As the core technology of the flexible pump, the impeller of the pump should have good elasticity, small deformation, and can withstand long-term high-frequency flexion without breaking or tearing. "Ten years sharpen a sword", the impeller elastomer technology determines the performance and durability of the pump. There are two kinds of impeller materials-sanitary nitrile rubber and EPDM; nitrile impeller is mainly used for vegetable oil, mineral oil, oil-containing medium and fields with high sanitation requirements; ethylene propylene rubber is mainly used for weak inorganic acid , organic acids, alkalis, salts, alcohols, ketones, sewage and a wide range of media.
